PLCnext Technology & PLCnext Controls

We are using an AXC F 2152 that we upgraded from 2024.0.2 to 2024.6
When enabling the Modbus Client TCP in the wbm, and rebooting the PLC we are getting the below error.

Please check if your PLCnext Engineer project includes a controller with version 2024.6 in the Project Tree.

Hello Theunis Mew,
Acccording to Error Mesage the „/opt/plcnext/projects/Default/Io/MbC/Default.mbc.config“ config data is not persists.
Additional Idea: Please open the folder „/opt/plcnext/projects/Default/Io/MbC/“ and check the „Default.mbc.config“.
The „Default.mbc.config“ must have the following content (you can create this config data and copy/past the content):

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

Thank you Eduard,
Creating the file and rebooting did the trick.
